osed between a Q reduced. 1p art ,Qof ,"thI V ber and a series of balls at with inner'and outer ball races 0 and 10 respectively being interposed between the housing and the shaft at the other end of the friction driving mem ber. It will be appreciated, however, that ball bearings may, if desired, be provided at each end of the shaft of the friction driving member.

The friction driving member is adapted to be driven from the starting motor through the medium of annular gearing which as il lustrated, comprises an internal gear formed in the end of the shaft of the friction driving member and a pinion 1" mounted on the end of the shaft 5 of the starting motor, the shaft 8 being arranged so that its axis is aligned with the axis hh and the centres of the internal gear 9 and the pinion 7 being spaced apart a distance corresponding with the spacing between the axes 72-72. and gg. By this arrangement the driving of the friction driving member will not be interfered with by the pivotal movements of the housing 6 and the internal gear 9 and the pinion 7" will remain in mesh for all positions of housing. If desired the posi-" tions of the internal gear and the pinion may be reversed so that the pinion is formed or mounted on the shaft of the friction driving member and the internal gear is formed or mounted on the shaft of the starting motor. A suitable form of free wheel, free wheel clutch or other means for preventing over-running of the starting motor may be provided for disconnecting the starting motor from the engine as the latter commences to function and increases its speed. The starting motor may be of the electric, petrol or air driven or other type, for instance, in-

ertia starter. In connection with inertia starters wherein the energy stored in a small flywheel accelerated to high speed by either manual or electrical means isexpended in rotating the flywheel of'the engine, a torque overload release must normally be provided but when applied to drive a friction starting devicein accordance with this invention the inertia starting motor need not be fitted with a torque overload release as the friction memdriving member and the other being co-axial with the housing.

2. A device for starting internal combustion engines comprising a rotatably mounted support, a friction driving member rotatably and eccentrically mounted in the support, means for rotating the support and means for driving the friction driving member, the latter means comprising annular gearing one of the members of which is co-axial with the support and the other being co-axial with the friction driving member.

3. A device for starting internal combustion engines comprising a rotatably mounted housing supported at each end thereof, a friction driving member rotatably and eccen trically mounted in the housing, means for rocking the housing about its longitudinal axis and'means for rotating the friction driving member comprising annular gearing, one of themembers of which is coaxial with the housing and the other being co-axial with the friction driving member.

i. An internal combustion engine comprising a flywheel and a starting device mounted adjacent the said flywheel, the said starting device comprising a substantially cylindrical housing rotatable about its longitudinal axis, a friction driving member rotatably and ec-. centrically mounted'in the housing, means for rocking. the housing about its longitudinal axis to cause the friction driving member to moveinto' and out of contact with the flywheel and means for rotating the friction driving member through the medium of annular gearing, one of the members of the latter being co-axial with the housing and the other being coaxial with the friction-driving member. 7 i i 5. An internal combustion engine comprising a flywheel and a starting device mounted adjacent the said flywheel, the said starting device comprising a starting motor, a substantially cylindrical housing rotatable about its longitudinal axis, a friction driving member rotatably and eccentrically mounted in the housing, means for rocking the housing about its longitudinal axis to cause the friction driving member to move into and out of contact with the flywheel and gearing for ro tating the friction driving member from the starting motor, the said gearing comprising a pinion on the starting motor shaft and coaxial with the axis of the housing and an internal gear on the friction driving member shaft and co-axial with the friction driving member.
